Problems solved by technology

[0004] In the process of realizing the above-mentioned washing machine, the inventor found that there are at least the following problems in the prior art: because the two drums are arranged up and down, this structure causes the center of gravity of the washing tub assembly 02 to be on the upper side
Therefore, during the working process, the centrifugal force generated by the rotation of the inner drums of the two drums will easily cause the washing tub assembly 02 to vibrate in different directions, and the four single damping shock absorbers 03 at the bottom of the washing tub assembly 02 can mainly reduce Its vibration in the up and down and left and right directions, but it cannot limit the left and right rotation swing of the washing tub assembly 02 around the hinge point of the second drum 022 outer cylinder and the single damping shock absorber 03, which causes local vibration of the washing tub assembly 02 Too large, easy to collide with the shell of the washing machine
The center of gravity of the washing tub assembly 02 can be lowered by adding a counterweight on the second drum 022 to reduce the local vibration above the washing tub assembly 02, but this increases the overall weight of the washing machine

Embodiment 1

[0046] Such as image 3 , Figure 4 and Figure 5 As shown, in this embodiment, the two upper washing tubs 22 are all set as pulsator-type washing tubs, so that the three-tube washing machine can take into account the advantages of the pulsator-type washing machine, saving electricity and time, and being able to add clothes at any time. The drum type washing machine has the advantages of saving water, less wear and tear, and high cleanliness. It is more convenient for users to choose which washing drum to use according to the type of clothes, washing requirements and other conditions.

[0047] Since two upper washing tubs 22 are arranged above the lower washing tub 21, this structure causes the overall center of gravity of the washing tub assembly 2 to be higher. Therefore, during the working process, the local vibration above the two upper washing drums 22 is relatively large, and it is easy to collide with the casing 1 . Therefore, the washing tub assembly 2 is preferably...

Embodiment 2

[0112] see Figure 25 , Figure 26 with Figure 27 , the difference between the three-barrel washing machine provided in this embodiment and Embodiment 1 is that: the two upper washing drums 22 are all configured as drum-type washing drums, and the two upper drums are arranged side by side, respectively located on the left and right sides, so that better utilization The horizontal space of the cabinet of the three-tub washing machine. In addition, compared with the scheme in which the upper washing tub 22 is a pulsator-type washing tub, since the openings of the two drum-type washing tubs face forward, the body height of the three-tub washing machine is relatively lower, which is suitable for shorter users. It will be more convenient when using two upper washing tubs 22.

[0113] see Figure 27 In this embodiment, since the motors driving the two upper washing drums 22 to rotate are installed behind the upper washing drum 22 and the rear motors 221 of the two upper washing...

Abstract

The invention discloses a multi drum washing machine, relating to the technical field of washing machines. The multi drum washing machine is designed to solve the problem that the local vibration above a washing tub component is so large that could collide with a case during the working process of the washing machine in the prior art. The multi drum washing machine comprises the case, and the washing tub component is arranged in the case. The washing tub component comprises a lower washing tub and at least one upper washing tub arranged on the lower washing tub, wherein the lower washing tub is a drum-type washing tub. The washing tub component is supported on a base plate of the case by at least one pair of combined shock absorbers, wherein each combined shock absorber comprises a main shock absorber and a sub shock absorber, the first end of the main shock absorber is connected with the base plate of the case, the second end of the main shock absorber is connected with the lower washing tub, the first end of the sub shock absorber is connected with the middle part of the main shock absorber, and the second end of the sub shock absorber is connected with the lower washing tub. The multi drum washing machine can be used for classification cleaning of clothes.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a multi-tubular washing machine. Background technique [0002] Nowadays, the classified cleaning of clothes has gradually entered the needs of users, such as the classified cleaning of coats and underwear, children's and adults' clothes. People often want to have a large-capacity washing machine and a small-capacity washing machine, but due to the limitation of the housing area, it is impossible to buy multiple washing machines, so the multi-tubular washing machine has emerged. Generally, multi-tub washing machines will have a large-capacity washing machine, and the remaining drums will have smaller capacities. [0003] Existing washing machines are generally as figure 1 The structure shown includes a housing frame 01, a washing tub assembly 02, four single damping shock absorbers 03 and four hanging springs 04, and the washing tub assembly 02 consists of a first drum ...
